Drawer Below Sink
As an Amazon Associate we earn from qualifying purchases. Details
A drawer below the sink is usually not a built-in drawer. The space under most sinks is an open cabinet with pipes in it, so the products sold for the job are add-on pull-out units that give you drawer-style access to the back of the cabinet. This guide compares five of them. Each Amazon listing was opened once on 2026-10-18, and every size, load figure, and fit rule below is the listing’s own statement. The numbers disagree in places, and where they do, both are shown. A drawer, in the furniture sense, is a storage box that slides out of a cabinet on slides or runners, and ball-bearing slides use steel balls to cut friction (Wikipedia, Drawer). Only one of the five below states that it uses ball-bearing slides.
Quick answer
Measure the cabinet interior first, because the five listings need very different space. REALINN states a minimum interior of 11 inches wide, 15 deep, and 16 high. PXRACK adjusts from 13.6 to 16.9 inches high. Vtopmart is the smallest, at 11.8 x 7.5 x 10 inches per unit. Biboraya expands from 15.3 to 24.2 inches wide and is the only one that names ball-bearing slides, but it says it does not suit cabinets with a middle partition. Madoalker lists 15.6 x 8.6 x 14.1 inches but also says it is for light to medium items. For similar guides, see this slide-out under sink guide, this two-tier under sink guide, and this kitchen under sink guide.
How the list was chosen
Each unit was included because its title says it pulls out or slides out and fits under a sink, and because it sits in the cabinet instead of being screwed into it. Full replacement drawer boxes, cabinet-door racks, and countertop organizers were left out. The picks cover five brands and five designs: a snap-together plastic unit, a clear plastic unit, two L-shaped metal units, and an expandable metal unit. Colour and pack-size variants of one listing are not counted as separate products. Prices and ratings are omitted.

Worked example: one cabinet, five checks
This example uses made-up cabinet measurements to show the method. It is not from any listing. Assume the cabinet interior is 30 inches wide, 21 inches deep, and 16 inches high, with no middle partition, and a drain pipe that blocks an 8 inch wide strip on one side of the floor.
- Height: 16 inches clears Madoalker (14.1), PXRACK (set it between 13.6 and 16.9, so up to 16), Vtopmart (10), Biboraya (12.9 to 15.4), and REALINN (needs at least 16, so it just passes).
- Width: with 8 inches lost to the pipe, about 22 inches of floor is left. Two PXRACK units are 11.8 inches wide each in the basket, which needs about 23.6, so only one fits side by side. Two REALINN units need at least 22 inches, which just fits.
- Depth: 21 inches clears the 15.9 inch PXRACK basket and REALINN’s 15 inch minimum.
- Expandable fit: Biboraya’s 15.3 to 24.2 inch range fits the cabinet width, but the listing also says it does not suit a cabinet with a bottom frame higher than 0.6 inches, which you would have to check by looking.
- Result: with the pipe in the way, REALINN is the unit that fits two across, and it does so with no slack. This is why the minimum interior in the listing matters more than the headline size.

Mistakes to avoid
Measuring the cabinet door opening and not the interior
REALINN sets its minimum on the cabinet interior, and Biboraya warns about partitions and raised bottom frames, which you cannot see from the door. Measure the floor space inside at its narrowest point.
Ignoring the pipe
Every unit here either has an L or C shape or says it shares space with pipes, but the clearance differs. Mark the pipe location on the cabinet floor before you choose.
Reading one weight figure as a per-drawer limit
PXRACK states 100 pounds and REALINN 50 lbs total. Vtopmart’s 15 LB applies to the top drawer. Biboraya and Madoalker give no number. Use the lightest stated limit for your heaviest items.
Fixing the unit in place before you decide the shelf layout
PXRACK and REALINN use suction cups or tape to hold the unit. Plan where each tier and basket goes before sticking anything to the cabinet floor.
Who should skip buying
- Anyone whose cabinet has a middle partition and who is considering the Biboraya unit.
- Anyone who needs a true built-in drawer. These are free-standing add-ons, not cabinet drawers.
- Anyone storing heavy items in the Vtopmart or Madoalker units; their listings say 15 LB (top drawer) and “light to medium”.

Only Biboraya names ball-bearing slides, with three silent rails on the bottom basket.
How much weight can they hold?

Do they fit around pipes?
PXRACK, Biboraya and REALINN describe L- or C-shaped designs that clear plumbing, and Vtopmart says it shares space with pipes. Madoalker says it fits most standard cabinets without naming pipes.
